Yesterday, I reported that Whitney Houston had entered an outpatient drug rehab program about 10 days ago. And just last week, she was spotted at a Prince concert. But it looks like she was attending many of his shows and his people got fed up with her demands and erratic behavior. Now, she’s banned because Whitney constantly demanded tickets and seemed to be on “full tilt” at all of his shows. And to top that off, she kept asking to go onstage with Prince but she was shot down because they were afraid of the outcome. One can only hope and pray Whitney get’s the help she needs.
